Ignition Coil + Spark Plugs for Chevrolet Aveo (2004-2008) 1.6L

Direct-Fit Ignition Coil and Spark Plug Kit for 2004-2008 Chevrolet Aveo 1.6L (T200/T250 / L91)

What it Does: The Ignition Coil and Spark Plug Kit restores secondary ignition voltage and combustion stability on the 2004-2008 Aveo to eliminate cylinder misfires and resolve rough idling.

The Stock Chevrolet Aveo Ignition Coil Breakdown

Under-hood thermal cycling on the T200 and T250 chassis quickly degrades the factory ignition assembly on the 1.6L L91 engine. Over time, internal epoxy potting breaks down, developing micro-fractures that cause dielectric punch-through and high-voltage arcing directly to the cylinder head. Concurrently, worn spark plugs with eroded electrode gaps create excessive secondary circuit resistance. This increased load overheats the coil pack driver circuits, triggering common P0300, P0301, and P0304 diagnostic trouble codes, poor fuel economy, and catalytic converter damage from raw fuel wash.

The Engineering Solution

This replacement ignition kit provides a matched secondary ignition overhaul designed to restore factory spark energy and dwell response. The coil pack replaces OEM interchange UF503 and features thermal-resistant PBT housing and high-dielectric epoxy fill to insulate against heat soak and voltage breakdown. Paired with factory-spec copper-core spark plugs, this kit maintains optimal primary-to-secondary resistance, ensuring complete fuel burn across all four cylinders, immediate throttle response, and extended ignition component longevity.
